Pre-service Teachers’ Perceptions towards Multicultural Education and Teaching of Culturally and Linguistically Diverse Learners

In this study the authors investigated 80 pre-service teachers about their perception towards multicultural education and teaching of culturally and linguistically underrepresented diverse students. Participants completed a modified version of the Diversity Orientations Survey. First, results show that the majority of pre-service teachers largely agreed for the need for the inclusion of multicultural education to teacher education program with regards to teaching linguistically culturally diverse students. Second, participants indicate lack of awareness with regards to understanding of multicultural education in terms of cultural awareness in the teaching of special needs students. This paper conceptualizes pre-service teacher’s perceptions towards multicultural education in general and discusses the teaching of culturally, linguistically and underrepresented diverse learners in K-12 schools. The authors propose reforms in the curriculum of teacher education preparation programs in colleges of education of inclusion of comprehensive multicultural education course at each level of education

Analysis of Risk Management Practices in the Oil and Gas Industry in Ghana. Case Study of Tema Oil Refinery (Tor)

Risk management refers to an interactive process consisting of steps, which when undertaken in sequence, enable continual improvement in decision making. The aim of risk management is to obtain understanding by all parties and agreement around what the risks really are and how they will be managed to improve performance, increase the value of firms and reduce financial distress .We used primary and secondary data in our analysis The study identified risks confronting Tema Oil Refinery (TOR) as instability in global oil prices, depreciation of the cedi against major currencies, health and safety, political interference, environmental pollution, brain drain, shortage of crude oil, huge debts as a result of subsidizing of petroleum products by government and default on the part of oil marketing companies to pay for products and  high operational risks .Other challenges as apathy on the part of staff to abide by safety rules was identified. TOR incorporates risk management in their strategic plan and have operations and Audit risk department but have been battling with effective implementation. Made recommendations to government and management of TOR on how to overcome the problems in implementing risk management in order to achieve the goals of the only refinery in Ghana.

Er3+ doped Silica-on-Silicon using fs-laser doping process for Integrated Waveguide Amplifier Platforms

Rare earth doped waveguide amplifier (EDWA) on silica-on-silicon (SOS) platform are area of great interest for silicon integrated photonics. We report the fabrication of erbium doped silica-on-silicon (SOS) wafer-scale platforms for integrated waveguide amplifier and laser application. We used a method named- ultrafast laser plasma doping (ULPD) process on silica- on-silicon substrates using erbium doped zinc-sodium tellurite glasses (TZN) as targets. The influence of laser energy on the doping process was studied in terms of the refractive index of the waveguides formed and their photoluminescence properties. Planar slab waveguides of refractive index1.64 at 633 nm and characteristic photoluminescence lifetimes of erbium at 1535 nm wavelength emission, varying from 13.38 ms to 10.52 ms were obtained. We used higher repetition rate (10 kHz) amplified Ti-Sapphire laser with pulse duration of 45 fs for faster and efficient growth of active waveguide layer in this research

Parasitic Load of Cattle Faecal Matter from Selected Farms in Kpong and its Health Implications

Cattle, one of the domesticated animals which are a potential source of parasitic contamination of land and water resources were studied to establish the parasitic load as a measure of quantifying the biological quality of land and water sources to determine the level of parasite load of the environment. A total of 180 faecal samples were collected from three farms in Kpong in the Lower Manya Krobo Municipality for the study. The samples were collected between 9 - 10 am when the animals released from kraal to be grazed and the faecal matter were collected as soon as it was dropped on the ground. The samples were collected with wide mouth plastic containers (about 500 ml) with lid. Samples were transported to the Water Research Institute Parasitology Laboratory for analysis. 10 g sample each was placed in a test tube and 10 ml of PBS was added to it. It was then processed and a drop was placed on a microscope slide and Lugol's iodine was added and observed under X 40 objective lens of the microscope. A total of 111 (61.67 %) out of the 180 faecal samples were found to contain the following parasites whilst 95 (85.59 %) had Ascaris sp., eight (7.20 %) had Strongyloides sp., one (0.90 %) had Trichuris erichiun and one (0.90 %) sample had Paragonimus sp. Five (4.50 %) samples had mix infections of Ascaris sp and Strongyloides sp. And 1 (0.90 %) sample had a mixture of Ascaris sp and T. berichiun. Infestation with Ascaris sp was found to be significantly higher (p > 0.001) than all the other parasites indicating that the animals are not often given worm expellants as expected and this can lead to zoonotic transmission of the parasite, as the cattle are reared on the same compound with the humans. This can affect the health of children as they played in the dung contaminated soils in their compound, thereby leading to absenteeism from school due to loss of blood from worm infestation leading to anaemia. The worm infestation can also lead to malnutrition and stunted growth in the children

Prevalence of Giardia species in Cattle Faecal Matter in Selected Farms in Weija and Kpong Major Water Supply Heads to Accra, Ghana.

In developing countries including Ghana, giardiasis plays a major role in gastroenteritis in vertebrate. It poses health and socio-economic burden, and continues to be one of the causes of infant and calf mortality. Their infection continues to thrive in humans due to the zoonotic transmission of infected domesticated animals including cattle, dogs and cats, and their con­tinual presence in water bodies. The objective of this study was to establish their presence and evaluate the prevalence of Giardia sp. in cattle faecal matter in the environment in the Kpong and Weija communities. The Iron-haematoxylin staining techniques was used to analyze the faecal samples in order to identify Giardia sp. (Student t- test and Chi square were the statistical analyses) used for the studies. About five percent (5.3%) prevalence was obtained in both com­munities and this was significant (p> 0.05). The parasite was found to be most prevalent (9.4%) in calves less than 3 months old and this decreased with age of calf. It was also observed that Giardia plays an important role in the cause of diarrhoea in cattle. There is the need to educate people on the disease and its implication on the quality of water from the treatment plants. Keywords: Giardia sp, water, contamination, diarrhoea, infant mortality

Detection of Human Genotype “B” Giardia lamblia in Ghanaian Cattle from Frafraha in Adentan Municipality of Ghana

Giardia duodenalis is a common intestinal parasite in humans, a wide range of domesticated and wild animals. There are human and animal specific, as well as zoonotic pathogenic gen­otypes. It is not clear whether livestock in close proximity to humans could be infected with human specific genotypes, and vice versa. In this study, Giardia-positive faecal samples were collected from both humans (n = 4) (from Maamobi Polyclinic in the Ayawaso Sub- Metro) and calves (n = 8) (from Animal Research Institute Farms, Adentan Municipality), in Ghana. Nested PCR amplification using Giardia-specific, Glutamate dehydrogenase (GDH) genes and Tri­osephosphate isomerase (TPI) gene primers for human and animal faecal samples respectively was carried out. Results showed that 100% of the calves carried the TPI-B genotype, which is a common pathogenic genotype in humans. This report is based on the unusual results obtained as Giardia duodenalis genotype B is known to occur in humans but is being observed in calves for the first time. This suggests that calves in close proximity to humans could be reservoirs and sources of human Giardia infections

Preservice training amid a pandemic in Ghana : predictors of online learning success among teachers

The coronavirus disease 2019 outbreak has brought the world to a standstill, especially the education sector. Globally, it has claimed over two million lives, with over 100 million people infected, forcing schools to close down. This has reignited the importance of online teaching and learning for preservice teachers who comprise the next frontiers in providing online education to their future students. However, studies on online learning [OL] success among preservice teachers in developing countries, such as Ghana, remain scarce. Accordingly, this study mainly aimed to assess the predictors of OL success among preservice teachers in Ghana. Bandura’s social cognitive theory guided the study; in total, 526 preservice teachers were recruited from four colleges of education. Although the teachers were ambivalent regarding the success of OL, significant differences were found between the following demographics: gender, specialization, marital status, the preferred mode of learning, and the place of residence. Moreover, the study discussed the need for intensive information and communications technology education among preservice teachers, particularly women, developing their confidence in computer skills, and other recommendations

Cross-national study of communal attitudes toward individuals with intellectual disabilities in sub-Saharan Africa : Cameroon vs. Ghana

Background: An intellectual disability (ID) is characterized by a deficit in the functional, cognitive, and adaptive skills required for independent living. Due to the low cognitive capabilities of individuals with IDs, they have become victims of marginalization, exclusion, and denial of their fundamental rights to basic necessities in societies around the world. While efforts are being made to improve service provision to and acceptance of individuals with disabilities, the extent of communal acceptance and recognition of these individuals as equal members of society remains underexplored in sub-Saharan African countries such as Cameroon and Ghana. Objective: As attitudes toward individuals with IDs are pivotal in shaping national policies, this cross-national study examined communal attitudes toward persons with IDs in Cameroon and Ghana. Method: The Community Living Attitude Scale for Intellectual Disabilities (CLAS-ID) was used to collect data from a total of 741 university students in the two countries. The validity of the scale was assessed using confirmatory factor analysis and principal component analysis. The association between the background variables and attitudes was examined using t-tests, analysis of variance, linear regression, and two-way factor analysis. Results: The results showed the validity of the CLAS-ID as a valid tool for measuring communal attitudes toward individuals with IDs in sub-Saharan Africa. The participants appeared ambivalent about attitude towards individuals with ID and other findings showed no association between attitudes and variables such as gender, relation, and contact with individuals with IDs. Conclusion: We discuss the need for innovative approaches aimed at changing attitudes toward individuals with IDs in sub-Saharan Africa as well as other study implications
